| Abstract: | Hybridizing experiment in Larix principis rupprechtii and Japanese larch was conducted.The pine cones,harvested from 22 controlled hybrids,ranged from 1.74 to 2.92cm in length,from 0.98 to 1.46cm in diameter.However,the other pine cones, from 30 hybrids,their cone-scale numbers ranged from 23 to 47,every 10 cones weight 5.2-16.3 grams,the seed wing from 0.75 to 1.07 cm long.1000-grain weight is 2.6-5.0 g. |
